can the direction of a light wave bent by the existence of a strong gravitational field?justify ur answer
4.Landline telephone networks are now interconnected using fiber optic technology. what are the optical fibers?what are its advantages over ordinary wiring? how does total internal reflection play a part in its function? does fiber optic technology have advantages?? cite examples
what is the principle behind tinted glasses?
I hate to break it to you but Einstein's Theory of Relativity explains exactly what you are asking. As for the technical stuff...good luck!!

Fiber Optic Cleaning Kit Cleaning Cube with Wipes 5 x Cards with Sealed Cleaning Zones Solvent Pen 2.5mm Port Cleaning Swabs Fiber Optic Use Fluke Networks' Fiber Optic Cleaning Kits to ensure all fiber end-faces are clean before every mating. Dirt, dust and other contaminants are the enemy of high-speed data transmission over optical fiber. Today's network applications require more bandwidth, making loss budgets tighter than ever. It is critical that all optical connections are clean and free of contaminants to ensure application success. Cleaning Kit Fiber Optic Cleaning Kit Fluke Networks NFC-KIT-BOX www.flukenetworks.com
The fifth edition of Fiber Optic Communications by Joseph C. Palais marks the book`s twentieth anniversary. In the 20 years since the first edition of the book was published, fiber optics systems have become more flexible and less costly and information capacity and transmission length have increased. This edition includes the many new and improved components and system architectures that have been added to the fiber-optic-communications designer`s tool kit. New component discussions describe Improved fibers that more fully utilize the optical spectrum Non-zero dispersion shifted fibers Graded-index polymer fibers Raman amplifiers Erbium-doped waveguide amplifiers Arrayed waveguide gratings Electroabsorption modulators Optical micro-electro-mechanical (MEMs) components Dispersion compensators Tunable light sources Tunable filters Small-form-factor connectors Non-adhesive splices Expanded coverage of system strategies and considerations include Optical time-division multiplexing Dense and coarse wavelength-division multiplexing Polarization mode dispersion External modulation The fifth edition also includes new problems, new figures, new worked examples, and an updated bibliography.

How to conectorize Plastic Optical Fiber - POF
How do I justify the choice of copper, optical fibre and radio links for the transmission?
How do I explain how a television signal might be distributed around a block of flats using copper cables, giving a justification for this choice of transmission medium including in my own explanation why UHF to VHF/VHF to UHF conversion is necessary.
Giving an explanation for using fibre optic distribution systems in hazardous environments. Explaining why a radio transmission system might be used instead of an infa red transmission system.
You might consider working this question a bit until it's more clear what you need to learn. Most people don't have to convince others to go copper and/or fiber in residential areas that include hazardous environments. As far as I know there is no such thing as UHF to VHF conversion. Info can be added to any frequency of transmission, but there's practical limits and costs considerations involved. But you do mention radio transmission vs. Infrared. The truth is, it's all about a carrier frequency whether it's UHF (Ultra High Frequency), VHF (Very High Frequency), RF (Radio Frequency), or Infrared Transmissionn (Just under visible light). Each have advantages and disadvantages depending on distance, line of sight, ambient RF noise, hazardous area, type of information transmitted, rate of transmition, etc. Check out the How Stuff Works Website and rephrase this if you can.
